You may know that the world was full of dinosaurs 99 million years ago, but did you know that crocodilian creatures were also in abundance? That’s right, the species – including crocodiles themselves – have made a living on Earth for an estimated 240 million years.

What reptiles lived with Dinosaurs in the Cretaceous period?

During the Cretaceous period, crocodiles were larger than today, but almost everything else about them is still the same. Another reptile that was living with the dinosaurs is the snake. The oldest snake fossils are nearly 160 million years old, which means they were alive and well when dinosaurs were ruling the Earth.

How many animals survived the mass extinction of dinosaurs?

The Mesozoic era brought forth more than 180 million years of dinosaurs until their extinction 65 million years ago. About 50 percent of the planet’s animal and plant life survived the Cretaceous-Tertiary mass extinction, also known as the K/T boundary. Here are some of the animals whose ancestors walked (or swam) alongside dinosaurs:

Can starfish survive out of the water?

No, starfish can’t survive out of the water. They will soon die if exposed to open air. These are water breathing and can use only their dermal gills present on the upper surface of the body to breathe. Their breathing mechanisms has a lot to explain about why they can’t survive for a much longer time when out of water.

So it comes as no surprise that living in its river flats and delta habitat, it is considered a dinosaur that ate fish. Whether its diet was made up of only fish, a combination of fish and aquatic birds and turtles, or whether it was opportunistic and hunted hadrosaurs when the chance came, we will perhaps never know for certain.

They are among the largest fish with some species reaching lengths of about 7–7.6 m (23–25 ft).

Why are there so many dead sawfish in the river Fraser?

In December 2018, the largest recorded mass fish death in the river occurred when more than 40 sawfish died, mainly because of heat and a severe lack of rainfall during a poor wet season. A 14-day research expedition in Far North Queensland in October 2019 did not spot a single sawfish.

What happened in the Cretaceous period?

The Cretaceous is the last of the three great ages of dinosaurs. To put it in a nutshell, dinosaurs appeared in the Triassic, grew to enormous sizes in the Jurassic and then spent the Cretaceous diversifying into any number of forms before their demise (which will occur in 10 million years time).
